Characteristics of a Good Test

What does reliability refer to in the context of a good test?

• Consistency of test scores on repeated administration

• The ability to measure what it is supposed to measure

• Ease of use for test administrators

• The time taken to complete the test

What is the ideal time interval for the Test-Retest method?

• 1 day to 1 week

• 15 days to 6 months

• 1 month to 1 year

• No specific time interval

What is the decision criterion for reliability in the Test-Retest method?

• 'r' must be negative

• 'r' must be +ve and high (r ≥ +0.5)

• 'r' must be exactly 0

• 'r' must be less than +0.5

What is the main threat of error in the Test-Retest method?

• Carry over effect

• Test length

• Group homogeneity

• Objectivity

What is the ideal gap between the first and second testing in the Parallel-form Reliability method?

• 1 day to 1 week

• 15 days to 6 months

• 1 month to 1 year

• No specific time interval

What is the suggestion for the Parallel-form Reliability method?

• Should be the last option to estimate reliability

• Proper care should be taken while developing equivalent test forms

• Use only one form of the test

• No suggestion is needed

What is the decision criterion for reliability in the Split-half method?

• 'r' must be negative

• 'r' must be +ve and high (r ≥ +0.5)

• 'r' must be exactly 0

• 'r' must be less than +0.5

What is the main threat of error in the Split-half method?

• Carry over effect

• Test length

• Group homogeneity

• Ambiguity of item

What is the suggestion for the Rationale Equivalence method?

• Should be the last option to estimate reliability

• Can be used effectively in research

• Use only one form of the test

• No suggestion is needed

What factors affect reliability according to the text?

• Time interval, test length, speed, group homogeneity, objectivity, ambiguity of item, inconsistency in administration

• Only test length and speed

• Only group homogeneity and objectivity

• None of the above
